FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig. 1)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the switch trigger. Release the
switch trigger to stop.
For continuous operation, pull the switch trigger, push in
the lock button and then release the switch trigger.
To stop the tool from the locked position, pull the switch
trigger fully, and then release it.
Speed adjusting dial
The belt speed can be infinitely adjusted between 3.3 m
and 16.6 m per second by turning the speed adjusting dial
to a given number setting from 1 to 6.
Higher speed is obtained when the dial is turned in the
direction of number 6, lower speed is obtained when it is
turned in the direction of number 1. Select the proper
speed for the workpiece to be sanded.
CAUTION:
• The speed adjusting dial can be turned only as far as 6
and back to 1. Do not force it past 6 or 1, or the speed
adjusting function may no longer work.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (Fig. 2)
For your own safety, always use the side grip. Install it by
screwing it firmly on the grip holder. The side grip can be
pivoted for easy operation.
Installing or removing abrasive belt
(Fig. 3)
Loop the belt over the front pulley. Hold the tool as shown
in the figure and press down to retract the front pulley so
that you can slip the other end of the belt over the rear
pulley. When pressing down the tool, be careful not to
allow the front pulley to turn unexpectedly, causing you to
lose control of the tool.
NOTE:
• The arrow on the inside of the belt and that marked on
the rear pulley must point in the same direction. (Fig. 4)
Connecting to Makita vacuum cleaner
CAUTION:
• Always close the nozzle cap when the vacuum cleaner
is not connected to the nozzle. Never insert your finger
into the nozzle. (Fig. 5)
Cleaner sanding operations can be performed by
connecting the belt sander to Makita vacuum cleaner.
6
When connecting to Makita vacuum cleaner, an optional
hose 28 mm in inner diameter is necessary. (Fig. 6)
When connecting to Makita dust collector (Model 420S),
the hose of the dust collector is not necessary. You can
connect the belt sander directly to the optional hose 28.
(Fig. 7)

OPERATION

CAUTION:
• Secure the workpiece with clamps, etc. if there is any
possibility of it moving during the work operations.
• The tool should not already be in contact with the
workpiece surface when you turn the tool on or off.
Otherwise a poor sanding finish, damage to the belt or
loss of control of the tool may result.
• When working with the tool, be very careful to avoid
any contact of the tool and belt with any part of your
body or anyone or anything near you.
Always use the side grip (auxiliary handle) and firmly hold
the tool by both side grip and switch handle during
operations. Turn the tool on and wait until it attains full
speed. Gently apply the tool to the workpiece surface and
move the tool forward and back. Press the belt only lightly
on the workpiece. Excessive pressure may damage the
belt and shorten tool life.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
Replacing carbon brushes
Remove and check the carbon brushes regularly. Replace
them when they are worn down to the limit mark. Keep the
carbon brushes clean and free to slip in the holders. Both
carbon brushes should be replaced at the same time. Use
only identical carbon brushes. (Fig. 8)
Use a screwdriver to remove the brush holder caps. Take
out the worn carbon brushes, insert the new ones and
secure the brush holder caps. (Fig. 9)
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
